SPECIFICATION forming part of Letters Patent No. 388,553, dated August28, 1888.

Application filed December 20, 1887. Serial No. 258.514. (No model.)

To all whom, it may concern.' l

Be it known that l, CHARLES W. GLIDDEN, of Lynn, county of Essex, andState of Massachusetts, have invented au Improvement in the Method ofAttaching Heels and Top Lifts to Boots or Shoes, of which the followingde` scription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

In nailing heels to soles in the manufacture of boots and shoes bymachinery it is customary to leave the heads of the nails exposed at theouter end of the attached heel and to there-1 after blind a top liftupon the protruding ends of the said nails. In some instancesthe'heelblank has been moderately compressed and nailed to the sole,leaving the heads of the nails liush, and thereafter a top lift has beenapplied to the protruding ends of the nails and it and the heclblanksubjected to pressure sufficiently to force the top lift upon theprotruding ends of the nails and at the same time compress the entireblank.

In nailing heels upon soles in nailing-machines the nails are usuallydriven partially into the heel before the heel is applied to the machineemployed to attach the heel to the sole.

Being desirous of improving the quality of the heel, especially as toits solidity, I have devised a method of attaching the heels to thesoles, which consists in first driving the par tially-driven nailsthrough the heel far enough to enter the sole, leaving the heads of thenails flush with the outer end of the heel, and immediately thereafterthe enti-re heel is subjected to such pressure as to compact and shortenthe heel upon the driven nails, the compression being sufficient toleave the heads of the nails protruding from the end of the compressedheel, and thereafter the top lift is blinded in usual manner upon theheel. By subjecting the body of the heel to its maximum pressure beforethe top lift or leather is applied thereto it is possible to maintainfor the top lift the shape given to it by the die used to cut out thetop lift, excessive pressure of the top lift being objectionable, andso, also, by compressing the stock of the heel after the nails have beenfully driven it is possible to make all the heels or the main bodiesthereof of substantially equal height and leave their the top lift, ashas heretofore been done, the

top lift cannot be as surely retained upon the heads of the nails as bythe improved method herein described and claimed.

Figurel in elevation shows a heel and a sufficient portion of aheelingmachine,whieh, taken in connection with the machine shown in myapplication, Serial No. 252,995, iiled October 2l, 1887, will enable myinvention to be understood. Fig. 2 shows the heel compressed orconsolidatedv upon the nails after the same are driven into the sole.Fig. 3 shows the top lift which is blinded upon the protruding ends ofthe nails; and Fig. 4 is a detail ou a larger scale of part of themechanism shown in Fig. l, the heel being broken out to show the innersole and last, against which the nails are driven.

Referring to the drawings, A represents a shoe-upper; B, its sole, and Ca heel to be applied to the said sole.

K represents the top'plate of the nailbox 7c.

7c represents oneof a series of drivers acted upon by a driverplate, L,said driver-plate having a hollow shank through which is eX- tended thepin or post k2 of the mailbox.

The trimmer-lever X, the die-bed spindle Z, its head Z", the shoulderedpin Z5, the spring Z, the stud or rod b, and the link b are all commonto my application referred to, Wherein the same parts are designated bylike letters, and in practice the parts referred to will be actuated asdescribed in the said application, that application describing fully ama` chine for carrying out the method herein described for attachingheels to soles.

In practice the heel C, it having been provided with the usual series ofnails partially driven into theheel, will be applied to the nailbox, theheads of the partially-driven nails entering holes in the mailbox, thedrivers be ing then down. In this condition the lasted shoe, with asuitable last, a, of iron or other material Within it, will be appliedto the usual jack-spindle, and the usual die-bed spindle, Z, common tothe McKay or other nailing machine, and fully shown in the saidapplication,

IOO

will be elevated, causing the drivers to ascend in the nail-box and actupon the heads of the nails 8 and drive the said nails through the heelC until the points of the nails pass through the soles, thus fasteningthe heel to the shoe, the heads of the nails being left flush with theouter end ofthe heel, as in Figs. l and 4. In

this condition ofthe parts, and as described in the said application,the nail-box 7c will be given au additional lift, as by link b', rod b,and shaft 7c", while the shoe remains stationary, the lift beingsufficient to compress the heel, or to cause it to move in the directionof its height upon the said nails, the latter remaining stationary, thecompression of the heel being sufficient to leave the head ends of thenails projecting from the end of the heel, as in Fig. 2. In thiscondition the usual die-bed spindle will be lowered, and a top lift, asT, will be placed between the usual top lift plate carried by thenail-box, or upon the nail-box itself, and the nail-box will then belifted, causing the top lift to be blinded in usual manner upon theprotruding ends of the nails. (See dotted lines, Fig. 2.)

In Fig. 4 the heel is broken away to show one of the nails, a, as fullydriven through the hcel by one of the drivers, k'.

Fig. 2 shows a number of nails left by consolidating the heel in thedirection of its height.

I claiin- The herein descibed method of attaching a heel and top lift toa sole of a boot or shoe, which consists in driving the nail from theheel into the sole to secu re the heel to the sole, and Whilethe heel isyet under pressure and the nails at rest further compressing the heelbodily in the direction ot' its length and of the nails, leaving theheads of the nails projecting from the end of the consolidated heel, andthereafter blinding the top lift upon the protruding heads of the nails,substantially as set forth.

In testimony whereof I have signed iny naine to this specification inthepresence of two suhscrihiug witnesses.

CHARLES NV. GLIDDEN.
